The CMS trigger system
(IOP Publishing, 2017-01)
This paper describes the CMS trigger system and its performance during Run 1 of the LHC. The trigger system consists of two levels designed to select events of potential physics interest from a GHz (MHz) interaction rate ...
Performance and operation of the CMS electromagnetic calorimeter
(IOP Publishing, 2010-03)
The operation and general performance of the CMS electromagnetic calorimeter using cosmic-ray muons are described. These muons were recorded after the closure of the CMS detector in late 2008. The calorimeter is made of ...
Search for a Vectorlike Quark with Charge 2/3 in t+Z Events from pp Collisions at √s=7 TeV
(American Physical Society, 2011-12)
A search for pair-produced heavy vectorlike charge-2/3 quarks, T, in pp collisions at a center-of-mass energy of 7 TeV, is performed with the CMS detector at the LHC. Events consistent with the flavor-changing-neutral-current ...
Search for New Physics with Same-Sign Isolated Dilepton Events with Jets and Missing Transverse Energy
(American Physical Society, 2012-08)
A search for new physics is performed in events with two same-sign isolated leptons, hadronic jets, and missing transverse energy in the final state. The analysis is based on a data sample corresponding to an integrated ...
Search for beyond the standard model Higgs bosons decaying into a bb‾ pair in pp collisions at √s=13 TeV
(Springer, 2018-08)
A search for Higgs bosons that decay into a bottom quark-antiquark pair and are accompanied by at least one additional bottom quark is performed with the CMS detector. The data analyzed were recorded in proton-proton ...
Search for massive resonances decaying into WW, WZ, ZZ, qW, and qZ with dijet final states at √s = 13 TeV
(American Physical Society, 2018-04)
Results are presented from a search in the dijet final state for new massive narrow resonances decaying to pairs of W and Z bosons or to a W/Z boson and a quark. Results are based on data recorded in proton-proton collisions ...
Time reconstruction and performance of the CMS electromagnetic calorimeter
(IOP Publishing, 2010-03)
The resolution and the linearity of time measurements made with the CMS electromagnetic calorimeter are studied with samples of data from test beam electrons, cosmic rays, and beam-produced muons. The resulting time ...
Search for long-lived particles decaying into displaced jets in proton-proton collisions at √s = 13 TeV
(American Physical Society, 2019-02)
A search for long-lived particles decaying into jets is presented. Data were collected with the CMS detector at the LHC from proton-proton collisions at a center-of-mass energy of 13 TeV in 2016, corresponding to an ...
Search for pair production of second-generation leptoquarks at √s = 13 TeV
(American Physical Society, 2019-02)
A search for pair production of second-generation leptoquarks is performed using proton-proton collision data collected at √s = 13 TeV in 2016 with the CMS detector at the CERN LHC, corresponding to an integrated luminosity ...
Radioactive source calibration test of the CMS Hadron Endcap Calorimeter test wedge with Phase I upgrade electronics
(IOP Publishing, 2017-12)
The Phase I upgrade of the CMS Hadron Endcap Calorimeters consists of new photodetectors (Silicon Photomultipliers in place of Hybrid Photo-Diodes) and front-end electronics. The upgrade will eliminate the noise and the ...
